Problems solved by technology

[0002] At present, in the field of desulfurization, the "glass flake lining coating (mastic)" used in the desulfurization equipment of steel structures, steel structures and the inner surface of concrete chimneys has a bond strength of 25MPa with steel structures, but the heat resistance of the coating is only 140°C. In the actual use process, the phenomenon of coating peeling due to short-term high temperature greater than 180 °C occurs from time to time, which directly affects the service life of the overall protective coating and the normal use of the desulfurization device and unit.

Abstract

The invention discloses an acid-resistant high-temperature-resistant corrosion-proof glue mud for an inner wall of a desulfurization device. The glue mud comprises the following raw materials by weight percent: 54.25%-56% of a phenolic epoxy vinyl ester resin polymer, 1%-2% of a cumyl hydroperoxide hardening agent, 33%-30% of glass flakes, 1%-0.5% of flake mica powder, 1%-0.5% of titanium dioxide, 0.5%-1% of an accelerant, 1%-0.5% of a thickening agent, 0.25%-0.5% of a de-foaming agent and 8%-9% of styrene. According to the glue mud, the phenolic epoxy vinyl ester resin polymer is adopted; a coating is good in resistance to high temperature, corrosion, solvent and oxidative high-concentration acid medium; compared with a similar product, the resistance to sulfur dioxide, sulfuric acid and vapor permeation is remarkably improved; the curing reaction is milder in comparison with that of methyl ethyl ketone peroxide; the heat value is lower, the hardening time is longer, the leveling and defoaming of the coating are facilitated, the electric spark breakdown resistance of the integral coating is improved, the construction operation is convenient, the materials are wide in source and easily available, and the comprehensive economic and social efficiency of the desulfurization device in the aspect of environmental protection is remarkably improved.
